Introduction

Po-Jung Chiang is a prominent inventor based in Zhongli, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 6 patents. His work focuses on innovative methods for improving semiconductor devices, particularly in the area of semiconductor-on-insulator (SOI) technology.

Latest Patents

One of Po-Jung Chiang's latest patents is a fabrication method of a metal-free SOI wafer. This invention involves various embodiments directed to forming a semiconductor-on-insulator (SOI) device with an impurity competing layer. This layer is designed to absorb potential contamination from metal particles during the annealing process. In this method, an impurity competing layer is formed on a dummy substrate, followed by the formation of an insulation layer over a support substrate. The front side of the dummy wafer is then bonded to the insulation layer. An annealing process is performed, allowing the impurity competing layer to absorb metal from the upper portion of the dummy substrate. Subsequently, a majority portion of the dummy substrate is removed, including the impurity competing layer, leaving a device layer of the dummy substrate on the insulation layer.
